Barracudas live primarily in oceans, but certain species, such as the great barracuda, live in brackish water. Due to similarities, sometimes Barracuda is compared with freshwater pike, though the major difference between the two is that Barracuda has two separate dorsal fins with a forked tail, unlike the freshwater pike. [6]
Great barracudas are large fish, and one of the largest of the Barracudas. Mature specimens are usually around 60–100 cm (24–39 in) in length and weigh 2.5–9.0 kg (5.5–19.8 lb). Exceptionally large specimens can exceed 1.5 m (4.9 ft) and weigh over 23 kg (51 lb).
Young barracuda drift inshore in spring, and move to deeper water in the late fall. Spawning season is from April until October off southern Florida. [14] Most Males mature at two years of age, and most females mature at three years of age. [14] In Sphyraena putnamae, the sex ratio observed of females:males was 1.49:1 respectively. [14]
Sphyraena chrysotaenia, the yellowstripe barracuda, is a species of predatory, ray finned fish from the family Sphyraenidae which is found in the Indo-West Pacific region. It has entered the Mediterranean Sea from the Red Sea through the Suez Canal as a Lessepesian migrant and is now an important species in the fisheries of the eastern ...
Sphyraena helleri, the Heller's barracuda, is a schooling species of barracuda in the family Sphyraenidae. [ 1 ] [ 2 ] [ 3 ] The species is named in honor of zoologist Edmund Heller [ 4 ]
The protruding lower jaw of the barracuda helps in its carnivorous feeding habits, aiding in catching slippery fish. The average weight of the Pacific barracuda is about 1–3 kg; their total length is about 1-1.1 m, rarely exceeding 1.2 m. Pacific barracuda have a distinctly forked tail-fin and widely-separated dorsal fins. [3]
Due to Hawaii's isolation 30% of the fish are endemic (unique to the island chain). [1] The Hawaiian Islands comprise 137 islands and atolls, with a land area of 6,423.4 square miles (16,636.5 km 2). [2] This archipelago and its oceans are physiographically and ethnologically part of the Polynesian subregion of Oceania.
They are normally around 30–60 cm (12–24 in) in length and weigh 3.6 kg (7.9 lb), but there are records of fish 165 cm (65 in) long and reaching weights of at least 12 kg (26 lb). [6] It is the largest species of barracuda in the Mediterranean.
